You base-ten people amuse me with your superstitious belief in the special power of numbers ending in "000". Had it not been for that big hunk of space rock that hit the earth some millions of years back, thus changing the course of evolution and allowing mammalia, not dinosauria, to become the planet's dominant animal class, the most highly evolved animals would be the descendents of dinosaurs, not shrews, and they'd have four digits on each appendage, not five, which means they would use a base-eight counting system, not the decimal system we use. In base-eight, your precious '28000' is '66540'. Not so special any more, is it?
